[QUOTE="burgunder, post: 1188089, member: 72783"] I have ready every jetting thread there is on the internet, twice (and there is a ton to read), but I am just looking for some insite and conformation that my discision is correct. The bike starts very easily without the choke and the rpms stop raising at about 2 1/4 turns out, so that is an indication to me that i need to go from the 40 pj to the 37.5. I am looking for the rpms to stop rising at around 1 1/2 turns out. And, from what i have read, the pilot jet does contribute to the jetting through every circuit, although mainly the 1st 1/8. If that doesn't clean it up, I will try the 2nd clip (I am on the 3rd right now.) After riding the plug is wet and black all over. I know that may indicate that I need a hotter plug, but with the riding I do in PA, the terrain changes so much -from very fast open conditions like a mx track to very slow trials type riding- I would rather error on the side of caution. It is not fouldling the br9eg(S) so I will stick with that, and try to clean up the jetting. PT cr - what is the 43-74 needle. I am running the 07 needle (forget the number) but, is that leaner or richer. [/QUOTE]
